It would help if the OP narrowed down his prop requirements/wishes. Currently it is open to many many recommendations where the sky is the limit . . . aka Autoprop by Brunton.
For years, I hummed and hawed trying to find reason to replace my 2 bladed fixed prop with either a folding or feathering 3 bladed prop. I thought I had a J Prop all lined up but frustratingly that fell through. In the end, I just could not find reason to layout $2.5K to $5K on a prop for my cruising needs. I ended up with a 3 bladed fixed prop ($325) from
Boat Propellers - New Boat Props for Sale - Get A Prop (and for whatever reason it is also named
Olympic Propeller Co. – Anacortes, WA ). Finanacially it was no big whoop. I am satisfied with the way it punches through the slop out in the Strait of Georgia and Juan de Fuca and don't see a noticeable difference in sailing speeds. But man it sure is fun to spend someone elses money.
